        <cfset xlsFirstTable.easy_getCell(evaluate(row + 1), evaluate(column)).setValue(

        <cfset xlsFirstTable.easy_getCell(evaluate(row + 1), evaluate(column)).setStyle(xlsStyleData)>

<!-- Set column widths -->

<cfset xlsFirstTable.setColumnWidth(2, 70)>
<cfset xlsFirstTable.setColumnWidth(3, 100)>

<cfset ret = workbook.easy_WriteXLSXFile("C:\Samples\Tutorial06 - protect Excel sheet.xlsx")>

<!-- Confirm the creation of Excel file -->
<cfset sError = workbook.easy_getError()>
